About XMCD
Mathcad lets engineers write calculations as they’d write them on paper, equations, units and text side by side on a page, and works them out as they type. Mathcad 12 moved its worksheets to XML in 2004, and every version to Mathcad 15 saves an XMCD, the calculations behind countless beams, circuits and pipelines.
Inside, an XMCD is one XML file: each region where it sits on the page, its math as a tree of operators, the result Mathcad last worked out with its units and number format, its text with its styles, and each plot and picture as the picture Mathcad drew of it, in base64.
Filepeek reads it in your browser and lays it out on its pages: each equation typeset where Mathcad put it, its results as Mathcad saved them, never worked out again, its programs, matrices and units, the text in its fonts and the plots as Mathcad drew them. A region turned off in Mathcad shows faded and an error in red. Zoom in or out, and Export saves the worksheet as PDF, a page for each page.

Questions
How do I open an XMCD file without Mathcad?
Drop it on this page or choose Peek an XMCD. Its pages show as Mathcad laid them out, every equation, result, text and plot in its place, on a Mac, a phone or any computer.
Are the results worked out again?
No. Filepeek shows each result as Mathcad last worked it out and saved it, with its units and number format. Changing a value and seeing the results follow needs Mathcad.
Why is part of my worksheet faded or red?
A faded region was turned off in Mathcad, so it isn’t worked out, and a red one ended in an error, whose message shows when you point at it. Both show as the file saved them.
Can Mathcad Prime open it?
Yes. Mathcad Prime converts an XMCD into its own MCDX, which opens here too. A few regions Prime doesn’t have change on the way, so keep the XMCD.
Does it open MCD files?
No. Mathcad 11 and older saved MCD, a binary Filepeek doesn’t read. Mathcad 12 to 15 open one and save it as an XMCD, which opens here.
